3.2.2.3 Faults/Alarms: Type 1 Operation
The Faults/Alarms level is accessible from the Function Select menu. Faults/Alarms are
similar to Monitor functions. The Faults/Alarms level displays the current fault status of
the group being displayed. Press [
← ] or [ → ] to move between the Faults/Alarm groups:
• Modulator faults
• Demodulator faults
• Transmit interface faults
• Receive interface faults
• Common equipment faults
The current faults/alarms status is displayed on line 2 of the display in real time. Fault
status is displayed as a “+” or “-” for each parameter monitored:
• “-” indicates that no fault or alarm exists.
• “+” indicates that a fault exists, and will cause switching in a redundant system.
• A reversed contrast “+” indicates an alarm is active, but will not cause switching
to occur.
To display labels for individual faults or alarms, press [ENTER]. Press [
← ] or [ → ] to move
the flashing cursor to the fault or alarm to be identified. The label for that fault/alarm is
immediately displayed on line one of the display. [CLEAR] can be used to exit this level
of operation and return to the previous level.
